WebTypical u values for windows that are double glazed record a U-value of between 1.2 W/m²K and 3.7 W/m²K, while triple glazed windows are usually rated below 1 W/m²K. … WebIn theory a difference in U-value of 0.1 units corresponds to about 9 kWh/m² glass per year. The difference between 1.6 and 1.2 is 0.4 units. Thus the saving is (difference in U-value) x (additional consumption) x (area of glass) = 4 x 9 kWh/m² x 30 m² = 1.080 kWh/year. With an energy cost of 0.20 €/kWh the difference is 216 €/year.

WebAs of October 2010 it's been law that all replacement windows and doors in the UK must achieve a U-value of 1.8W/m²K or less. These are controlled and regulated by various local authorities and government approved agencies such as the BFRC, Certass, Build-Check and FENSA. Just Value Doors Ltd is registered and regulated by FENSA. WebWhen all these features are provided, modern double glazing has a centre pane u-value of 1.2. Triple glazing is generally supplied with an overall thickness of 28 – 44mm. A 28mm unit with 1 low-e coating will achieve a centre pane u-value of 1.3, in this configuration, triple glazing would not be more energy efficient than a double glazed unit.
